Description

[0001] The utility model belongs to the technical field of water chillers and related equipment, in particular to a water circulation filtering device for a water chiller. Background Art

[0002] With the development of society and technology, equipment in various fields has been greatly improved. Most industrial equipment requires cooling to operate normally. Without a cooling water circulation system, these equipment can easily burn out due to overheating. Therefore, the cooling water circulation system can ensure the normal operation of the equipment, reduce downtime and losses. Through the cooling water circulation system, water resources can be recycled and the demand for new water can be reduced. At the same time, after the circulating water is initially cooled, its temperature is lower, which can reduce the workload of the cooling equipment and save energy.

[0003] However, it still has the following disadvantages in actual use:

[0004] 1. The water circulation filter device of the existing chiller cannot remove the fine impurities and some anions and cations contained in the circulating water during use, so it is easy to scale and corrode the equipment during operation, and it will also affect the conduction efficiency of the cooling water;

[0005] 2. After long-term use, the filter screen inside the existing chiller cannot be quickly disassembled and replaced. At the same time, the machine needs to be stopped for disassembly and replacement during the replacement process, which makes it impossible to continuously filter the cooling water and affects the work efficiency. To this end, we provide a water circulation filter device for a chiller to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0033] See also Figures 1 to 5 The utility model is a water circulation filtering device for a chiller, comprising a front impurity cleaning cylinder 1 and a rear impurity cleaning cylinder 2 placed directly behind the front impurity cleaning cylinder 1, one side of the outer wall of the front impurity cleaning cylinder 1 and the rear impurity cleaning cylinder 2 is connected to a small particle filter cylinder 3 through a connecting pipe 5 respectively, and the other side end surface of the small particle filter cylinder 3 is connected to an ion filter cylinder 4 through the connecting pipe 5, and a locking bottom plate 102 is installed at the bottom of the front impurity cleaning cylinder 1 and the rear impurity cleaning cylinder 2, and a pressing groove 1021 is opened at the center position of the outer wall on both sides of the locking bottom plate 102.

[0034] Specifically, a water inlet pipe 101 is provided at the center position of the top of the front impurity cleaning cylinder 1 and the rear impurity cleaning cylinder 2, and a plug rod 1022 is fixedly connected to the front and rear ends of the upper surface of the locking bottom plate 102, and a sealing ring 1023 is bonded to the upper surface of the locking bottom plate 102. A clamping ring 103 is provided at the top of the inner part of the front impurity cleaning cylinder 1 and the rear impurity cleaning cylinder 2, and a metal filter screen 104 is provided inside the clamping ring 103. The bottom of the front impurity cleaning cylinder 1 and the rear impurity cleaning cylinder 2 is provided with a clamping groove 105 on both sides, and the front and rear ends of the bottom of the front impurity cleaning cylinder 1 and the rear impurity cleaning cylinder 2 are A slot 106 is provided, and compression plates 301 are provided on both side end faces of the small particle filter cartridge 3. A water dividing block 302 is provided at the internal water inlet end of the small particle filter cartridge 3, and the other side of the water dividing block 302 is filled with a cotton core 303. A drain pipe 401 is provided at the center position of the other side end face of the ion filter cartridge 4, and a nanomembrane mounting ring 402 and a filter membrane mounting ring 403 are respectively installed on both sides of the outer wall of the ion filter cartridge 4, a nanomembrane mounting ring 402 is installed on the inner side wall of the nanomembrane mounting ring 402, and a reverse osmosis membrane body 4031 is installed on the inner side wall of the filter membrane mounting ring 403.

[0035] Furthermore, the front impurity cleaning cylinder 1 and the rear impurity cleaning cylinder 2 have the same shape, structure, etc., and the various processing devices are connected by a connecting pipe 5. The cross-section of the pressing groove 1021 is an inverted T-shape, and the insert rod 1022 can be inserted into the interior of the slot 106 to play a limiting role. The sealing ring 1023 can increase the sealing performance of the locking base plate 102 after installation. The metal filter screen 104 can be limited by the retaining ring 103, and the larger impurities in the cooling water can be filtered out through the metal filter screen 104. The cross-section of the retaining groove 105 is an inverted L-shape, and the water diversion gear 302 can slow down the water flow speed and realize diversion. The cotton core 303 can filter out fine impurities in the cooling water, and the calcium and magnesium ions in the water can be cleaned under the action of the nanomembrane body 4021 and the reverse osmosis membrane body 4031 to reduce the hardness of the water.

[0036] The operation process of this embodiment is: first, cooling water is introduced into the front impurity cleaning cylinder 1 or the rear impurity cleaning cylinder 2 through the water inlet pipe 101, and after the cooling water enters, it is filtered by the metal filter 104 in the front impurity cleaning cylinder 1 or the rear impurity cleaning cylinder 2, and impurities in the cooling water can be filtered out by the metal filter 104, and the filtered cooling water enters the small particle filter cylinder 3 through the connecting pipe 5, and then the cooling water is separated by the water dividing gear 302 in the small particle filter cylinder 3 and enters the cotton core 303, and the small particle impurities in the cooling water can be filtered out by the cotton core 303, and then the cooling water enters the ion filter cylinder 4 through the connecting pipe 5, and the cooling water can clean the calcium and magnesium ions in the water under the action of the nano-membrane body 4021 and the reverse osmosis membrane body 4031 inside, so that the hardness of the water can be reduced, so that the cooling water does not scale in the tube wall during operation, and the impurities in the water and the hardness of the water are reduced, thereby avoiding the conduction efficiency of the cooling water from being reduced. Specific embodiment 2

[0038] See also Figures 5 to 6 On the basis of the specific embodiment 1, what is different from the first embodiment is that: an installation component 6 is provided, the installation component 6 includes a card plate 601 and a pressure block 602 installed at the bottom of its outer wall, and the bottom of the inner wall of the card plate 601 is fixedly connected with a connecting rod 603, which solves the problem that the filter screen used for filtering inside the water circulation filtering device of the existing chiller cannot be quickly disassembled and replaced after long-term use, and the machine needs to be stopped for disassembly during the replacement process, resulting in the inability to continuously filter the cooling water and affecting the work efficiency.

[0039] Specifically, the other end of the connecting rod 603 passes through the through hole on one end face of the fixed plate 605 and is connected to the limit plate 606. A spring 604 is sleeved on the outer side of the outer wall of the connecting rod 603. The spring 604 is located between the clamping plate 601 and the fixed plate 605. The outer wall of the fixed plate 605 is fixed on the inner wall of the pressing groove 1021.

[0040] Furthermore, the cross-section of the card plate 601 is inverted L-shaped and smaller than the size of the card slot 105. The card plate 601 and the limit plate 606 are connected by a connecting rod 603, which plays a role of connecting transmission and drives the card plate 601 to move under the elastic performance of the spring 604.

[0041] The operation process of this embodiment is as follows: after long-term use, there are too many impurities on the metal filter screen 104. At this time, the pressure blocks 602 located on the outer walls on both sides of the locking base plate 102 are pushed inward, and the pressure blocks 602 are forced to push the card plate 601 to move, wherein the inner wall of the card plate 601 is connected to the limit plate 606 through the connecting rod 603. Therefore, when the card plate 601 moves, the limit plate 606 will be driven to move under the action of the connecting rod 603, and the spring 604 will be squeezed. At this time, the card plate 601 can be moved out of the card slot 105 at the bottom of the front impurity cleaning cylinder 1 or the rear impurity cleaning cylinder 2, and then the front impurity cleaning cylinder 1 or the rear impurity cleaning cylinder 2 can be pulled out upward, and then the metal filter screen 104 can be removed from the clamping ring 103 inside the front impurity cleaning cylinder 1 or the rear impurity cleaning cylinder 2 and replaced. The same is true when installing. First, remove the front impurity cleaning cylinder 1 1 or the slot 106 at the bottom of the rear impurity cleaning cylinder 2 is aligned with the insertion rod 1022 on the surface of the locking base plate 102, and the top of the card plate 601 is inserted into the card slot 105, and then the force on the pressure block 602 is stopped. At this time, the card plate 601 is rebounded to the initial position under the elastic performance of the spring 604. Since the cross-sections of the card plate 601 and the card slot 105 are both L-shaped, the locking base plate 102 can be clamped at the bottom of the front impurity cleaning cylinder 1 or the rear impurity cleaning cylinder 2 through the card plate 601, so that the staff can quickly disassemble and replace the metal filter 104. At the same time, when replacing the metal filter 104 in one of the front impurity cleaning cylinder 1 or the rear impurity cleaning cylinder 2, the metal filter 104 in the other cleaning device can be used to filter the cooling water, so as to achieve the effect of continuous filtering of the cooling water and improve work efficiency.
